18. Are pre-treatment sediment filters required in an arsenic treatment system?

DEP strongly recommends a 5-micron pre-treatment sediment filter to prevent any dirt or geologic materials coming up from the well from clogging or fouling the arsenic water treatment equipment.
If a water softener or other treatment unit capable of removing dirt or other particles will be located before the arsenic water treatment unit, and the well water is not especially dirty, then the pre-treatment sediment filter can be considered optional.
